In response, TI has unleashed a torrent of demand letters claiming that the anti-circumvention provisions of the Digital Millennium Copyright Act (DMCA) required the hobbyists to take down commentary about and links to the keys. "This is not about copyright infringement. This is about running your own software on your own device — a calculator you legally bought," says EFF Civil Liberties Director Jennifer Granick. "Yet TI still issued empty legal threats in an attempt to shut down discussion of this legitimate tinkering. Hobbyists are taking their own tools and making them better, in the best tradition of American innovation.""
